Application ined october 21,1901. stanno. 79.4.61. (Nomads.)

To @ZZ whom, it may coi/accrul p Be it known that I, WILLIE H. C.SCHUBERT, a citizen of the United States,residin g at Britt, in thecounty of Hancock, State of Iowa, have invented certain new and usefulImprovements in Plows; and I do hereby declare the following to be afull,clear, and exact descripa tion of the invention,such as will enableothers skilled in the art to which it appertains to make and use thesame. l

This invention relates to plows in general, and more particularly to theclass of plows known as disk plows, the object of the in-` vention beingto'provide a simple and efficient construction of this nature whereinthe angle of the disk may be varied and reversed, as also the degree anddirection of pitch thereof.

A further object of theinvention is to provide a construction'which willpermit of ad-k justment of the parts easily and quickly without theoperator leaving his seat, so lthat the parts may be shifted at the endof each row, other objects and advantages of the invention havingreference to details of construction, which will be understood from thefol-4 i lowing description.

In the drawings forming a portion of this specification, and in whichlikenumerals of reference indicate similar parts in the several views,Figure 1 is a side elevation of the plow with the disk in a verticalplane, as when transporting the implement from place to place. Fig. 2 isa rear elevation of the plow with one side of the frame thereof loweredto give a corresponding pitch to the disk. Fig; 3 is a detail view ofthe disk with the mechanism for adjusting it rotatably to vary the widthand direction ofthe furrow.

'Referring now Ato the drawings, there is shown a plow comprising aframe including an axle 10, having the straight end portions 11 and 12,forming spindles, on which are mounted the supporting-wheels 13 and 14,the portion between the spindles being curved upwardly to form the arch15, Y

The wheels 13 and 14 are the front wheels of the implement, the rearWheel-of the implement being a caster-wheel 16, the easter 17 of whichis journaled at its upper end in a suitable bearing at the rear end ofthe plowbeam 18. At a point somewhat in advance of the middle of theplow-beam are pivotally connected the braces 19 and 2O through themedium of a collar 21, engaged in a circumferential groove formed in thebeam,the outer or opposite enuds of the braces being connected to thesides of the arch 15. Connected also to the beam, but'rigidly, are thearms 21 and 22, which diverge in the direction of the axle, beneathwhich their outer ends are passed.` the extremities of these outer endshaving upwardl'y-c'lirected and spaced fingers 23 and 24, between eachpair of which is disposed one of the spindles of the axle, as shown. anangular' lever '25,` provided with a handle portion 26 for rocking itand havinga trigger 27, with which is connected the pawl 28 forengagement with the notched segment 29 for Vholding the lever atdifferent points of its pivotal movement. The opposite end of the leverhas a link 29' connected lheretowl1ich link4 Upon each side ofthe archispivoted in turn is connected, through the medium of the bail 30, withthe upper ends of the fingers of the adjacent arm. If, then, one'ofthese levers 25 be raised and the other lowered, one arm will be raisedand the other lowered and the plow-beam will be tilted laterally, Whileif both levers are similarly positioned the beam will be held level.

vThe disk of theplow is shown at 35 and is rotatably mounted upon thespindle 36 at the Vlower end of the shaft 37, the upper end of which ispassed through a bearing 38 in the plow-beam in the rear of the 'pointof connee tion of the braces 19 and 20 therewith, and

.concentric with which shaft is arranged a notched segment 2l. A lever22 is fixed to the upper protruding end of the shaft and carries atrigger 23', connected to the pawl 24s, upon the lever and arranged toengage the notched segment to hold the lever at different points of itsadjustment.

By manipulatingv the lever the shaft may be rotated and the connecteddisk may be moved to reverse or vary its angles to the beam.

In practice when a furrow is to be made one of the levers 25 is raisedandthe other' lowered, the disk having been adjusted to throw the furrowin the proper direction, and when the .endlof the furrow is reached theproper lever is oppersrated` to right theimplement, and while the plowis being turned the disk may be reversed for` the return furrow.

Itwill be understood that in practice modifications of the specificconstruction shown may be made and that any suitable materials andproportions may be used for the various parts Without departing from thespirit of the invention.

What is claimed is- 1. A plow comprisinga beam having a disk connectedthereto for adjustment in a horizontal plane, an axle havingsupportingwheels, rods connected to the axle and having pivotalconnection with the beam, arms connected to the beam, and extending atopposite sides thereof and below the axle, and levers pivoted to theaxle and connected to the arms for raising and lowering the latter totilt the beam and therewith the disk in opposite directions.

2. A plow comprising an arched axle provided with supporting-Wheels, abeam having a disk connected thereto for adjustment in a horizon talplane, braces connected to the arch and having pivotal connection withthe beam, arms connected to the beam and extending at opposite sidesthereof and having ingers directed upwardly at opposite sides of theaxle, and levers pivoted to the axle and having connections ,with thefingers to adjust the arms and tilt the beam and therewith the disk.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIE H. C. SCHUBERT.
